Exercise: Judging colour temperature 1

This exercise is to examine the effect of natural light on the overall temperature of an image. We are to take three images, the first in sunlight when the sun is high in the sky, the second again when the sun is high in the sky but in shade, and the final image in sunlight at the end of the day when the sun is low in the sky. All images were taken with the Light Balance set to daylight.

The first image shows a good rendition of what was in the viewfinder at the time. The overall colour balance is fairly accurate in terms of the reds and blues.

The second image, taken with the same settings and time of day but in the shade and show a definite blue tinge to the skin and hair. Here the reflections from blue sky have influenced the overall colour. I wish I had taken an image with the white balance at shade to see it compensated.

The final image was that taken at the end of the day when the sun was low and richer in reds. These have influenced the overall colour and given it a much richer and warmer colour.

Please note the written exercise asked for an additional 9 images but did not detail them. It also referenced pictures of wallabies that were not in the course notes, I think that there has been an update to the noteswithout updating the exercise and I was therefore unable to complete any more.
